Summary: Did Brigham Young attempt to suppress and destroy all copies of Lucy Mack Smith's Biographical Sketches of Joseph Smith because it contained information which would embarrass the Church? It is claimed that Brigham Young inserted the reference to Joseph Smith's First Vision into Lucy's book. Critics also try to prove that the silence of Joseph's mother and siblings in her history prove that the First Vision did not take place, and is a later fabrication by Joseph, and not well known to the early members of the church.
